High Efficiency RO/DI Systems

[wingedfish]

In BC where most (if not all) water is gravity fed, the growing areas have high pressures for the farmers and the houses have pressure regulators. On the prairies, all municipal water is fed by pumps and it is not cost efficient to supply high pressure water and so no need for pressure regulators. Stuck with what the city gives you.

Also, if you figure the price to run that booster pump in electricity and initial cost, you may find the cost of the water might be cheaper.

Rain collection into a barrel filtered and then pumped into the ro might be worth it, but a quarter of a 55G drum at prairie rain rates makes for few and far between water changes.

Cost of water and low efficient RO systems is at this point, a necessary evil of the hobby. 1:1 sounds great, but I'm skeptical.
